Balcombe Street Siege - The Siege

The Siege

The four men ended up in a flat at 22b Balcombe Street in Marylebone, taking its two residents, John and Sheila Matthews, hostage. The men declared that they were members of the IRA and demanded a plane to fly both them and their hostages to Ireland. Scotland Yard refused, creating a six-day standoff between the men and the police. Peter Imbert, later Commissioner of the Metropolitan Police, was the chief police negotiator.

The men surrendered after several days of intense negotiations between Metropolitan Police Bomb squad officers Detective Superintendent Peter Imbert and Detective Chief Superintendent Jim Nevill, and the gang’s leader Joe O’Connell, who went by the name of “Tom”. The other members of the gang were named “Mick” and “Paddy”, thereby avoiding revealing to the negotiators precisely how many of them were in the living room of the flat. The resolution of the siege was a result of the combined psychological pressure exerted on the gang by Imbert and the deprivation tactics used on the four men. The officers also used carefully crafted misinformation, through the BBC radio news—the police knew the gang had a radio—to further destabilize the gang into surrender
